碩士 === 國立臺灣科技大學 === 營建工程系 === 104 === After the completion of civil construction, such as buildings, transportation construction, bridges, etc., often require long-term monitoring of its electronic monitoring equipment quality and safety. In this research project inside the building common smoke detector to plan a long time monitoring devices, can be timed to collect monitoring data and management information daily environmental sensing devices, as well as immediate emergency treatment, build a low-cost, wide-area wireless monitoring system. Take low-cost, convenient access to equipment design approach, allowing various areas of engineering or technical personnel can always be applied to their own needs. Usually smoke detectors and smoke alarms is only responsible for detection, there is no networking function. When an emergency occurs, not immediately know the location and status of smoke detectors occurring in people at a distance, and even sometimes imperceptible changes in temperature or siren was cut off wall, losing an emergency first time disposal of opportunity that people in dangerous environments, and even loss of life. A networking sensor networks, typically the mains, when faced with an emergency situation or prospective loss of power, sensor system suddenly lost the original function of networking, each one sensing device will lose power or an independent sensing device only. So we want to establish a wireless sensor network system can be used in case of power failure, when power outages in the city can continue its normal operation for several hours or more, so that personnel in emergency situations to be out of danger in the effective time situation. When the device has a networking function, the monitoring system can collect its information and control, but when the device is unable to obtain effective power of the case, it will use the battery can be appropriate and effective energy and communications, in order to extend the wireless sensing device monitoring aging. Therefore, low-power material component selection, the device between the Internet function with each other, only the low-power design time monitoring apparatus and an effective monitoring program in order to effectively extend the device. To Implement the advanced fire-alarm and evacuation-signing system, the entire system can be divided into two parts advanced fire-alarm device and evacuation-signing system. Provide basic functions of smoke detectors in advanced fire-alarm device, the new Bluetooth wireless mesh network can monitor the status of every device, and to provide escape of direction, daily temperature and battery level, and more. In the evacuation-signing system uses an embedded PC, which designed the database, the device configuration settings page and device monitoring program, you can collect daily information storage and transmission to the central control system, the evacuation-signing system can smoke in accordance with the state the device to dynamically change every advanced fire-alarm device escape of direction, so that people can know immediately the direction and orientation, to achieve the minimum damage to persons and property.
